Troubleshooting

Everything is hooked up but nothing is working. What should I do?

When you troubleshoot issues with an MST hub, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Video cables

  • Video source

  • Video destination

  • MST Hub

To test your setup components, try the following:

  • Use the video cables, video source, video destination, and MST hub in another setup to see if the problem is with the components or the setup.

  • Use a different video cable, video source, video destination, and MST hub in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

  • Eliminate the use of adapters, extenders, or splitters where possible.

When you test the MST hub with your computer system, do the following:

  • Make sure that the computer/graphics adapter is MST compatible. For more information, refer to the following FAQ: http://www.startech.com/faq/mst-hubs-gpu-compatibility.

  • Make sure that the latest graphics drivers are installed. The latest drivers are available on the website of the manufacturer of the graphics adapter.

  • Use compatible adapters. For example, DisplayPort to HDMI and not HDMI to DisplayPort.

Note: Drivers are not required for the MST hub.
